spiral staircase for loft

The first and the last joist will be in hangars and also screwed into the wall studs. They basically become just like the first ledger only shorter.

Space the studs out even, 12 or 16" is code.

When you pick a screw remember the length of the screw is twice the length of what your screwing through. So when you screw through 1.5" 2x4 you want a 3" screw but remember now you're screwing through drywall also. That's why I recomend 4" screws for the three ledger boards.

I dont understand what your talking about laying down first?

You do not want a 22 inch step. Uneven step heights get folks hurt. Your brain ain't ready for steps to change heights and you trip falling down the stairs.. its BAD.

I had a home owner btching to the inspector one time that one step was 1/8th inch higher and how dangerous it was. The inspector looked at him and said "it's fine, maybe you should go inside".... I think the inspector didn't want me to bash the guy with my hammer....

No need for hangars on the cap end. The ends get tied together with short blocks then the entire thing gets capped making it very solid.

Remember this is built like a deck but its tied into a closet that I cant see the framing on and have no idea how well its built. This is for kids, not storing engine blocks or dance partys....

Best of luck and post lots of pics as you build it so I and the rest can see how it looks.

In fact I'll send you my number and you can call me with any questions as I'll be working and not checking this site.
